今天的主要工作就是将数据处理的客户端部分完成，从同学写好的安卓交互程序中读取用户名和密码等信息，并将其提交给我的服务器后台程序处理，并读取反馈信息反馈给用户交互模块，主要涉及到http连接以及json数据的处理等内容。
主要代码
private Handler handler=new Handler(){
public void handleMessage(Message msg){
switch (msg.arg1) {
case 1:
my_json mj;
mj=take_json(resultData);
Toast toast=Toast.makeText(getApplicationContext(), mj.id+" "+mj.state+" "+mj.code, Toast.LENGTH_SHORT);
toast.show();
//mTextView.setText(mj.id+" "+mj.state+" "+mj.code);
break;
default:
break;
}
}
};
class my_json
{
public int id;
public String state;
public String code;
}
private my_json take_json(String JSON)
{
my_json mj=new my_json();
try {
JSONTokener jsonParser = new JSONTokener(JSON);
// 此时还未读取任何json文本，直接读取就是一个JSONObject对象。
// 如果此时的读取位置在"name" : 了，那么nextValue就是"yuanzhifei89"（String）
JSONObject person = (JSONObject) jsonParser.nextValue();
// 接下来的就是JSON对象的操作了
mj.id=person.getInt("id");
mj.state=person.getString("state");
mj.code=person.getString("code");
} catch (JSONException ex) {
// 异常处理代码
}
return mj;
}
